total void content is minimal. X-ray methods are the predominate method for solder void analysis but this method can be quite subjective for non grid array components due to the two dimensional aspects of X-ray images and software limitations.

Copper K-α is an x-ray energy frequently used on labscale x-ray instruments. The energy is 8.04 keV, which corresponds to an x-ray wavelength of 1.5406 Å. …
The anode is mounted on a hollow rotor, which contains two ball bearings. The inner race of both bearings is located on an anode shaft. Between the inner and outer races of each bearing is a circular row of balls in a bearing cage. The surfaces of the cage in frictional contact with the balls is coated with a layer (I) of silver forming a lubricant; and the silver (I) is covered with a layer ...

The Avogadro constant (symbolized as NA) makes it easier to express the huge amount of atoms or molecules in a material. In the current SI, the Avogadro constant ( NA) is technically defined as the number of carbon-12 (carbon atoms with a total of 12 protons and neutrons) in 12 grams. That number is equal to about 6.022 x 10 23 carbon-12 atoms.

The 4600-W Bondtester is a benchtop system designed test semiconductor wafers using a robot handler. Test an entire casette of wafers without operator input. The system can automatically complete shear and pull test patterns with different orientations of bonds, while recording failure mode images after test.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
• Stack multiple solder balls to increase solder volume – chip-on-board with 100µm balls – large pads on PCBs need more solder than 100µm ball provides – place balls on PCB and reflow – add underfill stack of 14 solderballs of 60µm diameter before and after reflow Chip-on-Board 5x6mm² PETA6SE ASIC with 100µm balls and 500µm pitch
Copper pillar pull. Copper pillar is rapidly being adopted as a bumped wafer interconnect. The construction is that of a Copper cylinder around 50µm in diameter and height, topped with a dome of solder. As with any interconnect the quality of the bonding process between the different parts is vital for the reliability of the finished product.
